NS Series Programming Manual
If the display position is written directly to $SW2 and $SW3, the pop-up screen will move to the speci-
fied position.
The display size is limited so that the pop-up screen does not protrude outside the screen display
range. The display position will be such that the whole pop-up screen is displayed.
If pop-up screens are moved while the screen saver is displayed, the screen saver will be canceled.
The display position when pop-up screen 1 is opened cannot be specified using $SW2 and $SW3.
Current Pop-up Screen 2 Number ($SW4)
$SW4 stores the screen number for the current pop-up screen 2. (Stored in BCD or binary.)
The value “0” will be stored in $SW4 if no pop-up screen is open.
If a screen number is written to $SW4, that pop-up screen will be displayed.
The display will not switch to that screen, however, if that screen does not exist or if it is a base screen.
In such cases, no error message will be displayed but the system will change the screen number
stored in $SW4 back to the original screen number.
If pop-up screens are opened and closed frequently, the display update may take some time and
communications may be delayed.
The pop-up screen will close if 0 is written to $SW4. Also, 0 will be set for the pop-up screen display
position ($SW5 and $SW6).
If a pop-up screen is opened, closed, or switched while the screen saver is displayed, the screen saver
will be canceled.
Position of Pop-up Screen 2 ($SW5 and $SW6)
$SW5 and $SW6 store the display position for pop-up screen 2. (Stored in BCD or binary.)
The upper left X coordinate for pop-up screen 2 is stored in $SW5 and the upper left Y coordinate is
stored in $SW6.
If the display position is written directly to $SW5 and $SW6, the pop-up screen will move to the speci-
fied position.
The display size is limited so that the pop-up screen does not protrude outside the screen display
range. The display position will be such that the whole pop-up screen is displayed.
If a pop-up screen is opened, closed, or switched while the screen saver is displayed, the screen saver
will be canceled.
The display position when pop-up screen 2 is opened cannot be specified using $SW5 and $SW6.
Current Pop-up Screen 3 Number ($SW7)
$SW7 stores the screen number for the current pop-up screen 3. (Stored in BCD or binary.)
The value “0” will be stored in $SW7 if no pop-up screen is open.
If a screen number is written to $SW7, that pop-up screen will be displayed.
The display will not switch to that screen, however, if that screen does not exist or if it is a base screen.
In such cases, no error message will be displayed but the system will change the screen number
stored in $SW7 back to the original screen number.
If pop-up screens are opened and closed frequently, the display update may take some time and
communications may be delayed.
The pop-up screen will close if 0 is written to $SW7. Also, 0 will be set to the pop-up screen display
position ($SW8 and $SW9).
If a pop-up screen is opened, closed, or switched while the screen saver is displayed, the screen saver
will be canceled.
Position of Pop-up Screen 3 ($SW8 and $SW9)
$SW8 and $SW9 store the display position for pop-up screen 3. (Stored in BCD or binary.)
